ROTARY ENGINE.

SPECIFICATION forming part of Letters Patent No. 327,621, dated October 6,1885.

Application filed May 11, 1885. Serial No. 165,012.

` To @ZZ Lu/"tom it may concern,.-

Be it known that I GEORGE E. 'Touw-3R, a citizen of the United States, residing at Newport, in the county of Barton and State of Missouri, have invented cert-ain new and useful Improvements in Rot-ary Engines; and I do hereby declare the following to be a full, clear, and exact description of the invention7 such as will enahle others skilled in the art to which it appertziins to make and use the same, reference being had to the accompanying drawings, and letters of reference marked thereon, which form a part of this specification.

Likeletters refer to similarparts throughout the several views.

My invention relates to that class of rotary engines employing sliding valves in connection with a wheel provided with an annular steampassage in its periphery; and the novelty consists in certain novel features of construction and arrangement of parts, hereinafter more fully described and claimed.

Reference being had to the accompanying drawings, Figure l is a longitudinal vertical section vof the cylinder and steam-wheel,.show ing the steam-valves, the guiding cam-groove in the head of the cylinder being indicatedin dotted lines. Fig. 2 is a vertical transverse section through the center ofthe engine, taken on line as m of Fig. 1. Fig. 3 is a section on line y y of Fig. 1, showing the packing-block in position. Fig. 4 is a section on line a .e of Fig. l. Fig. 5 is a perspective view of one of the valves detached.

A represents a stationary cylinder, within which the solid drum or steam-wheel B revolves, the same being secured to the powershaft C, which passes through and has its bearings at C and C upon the outside of the eylii der. At one end of the power-shaft the pulley or band wheel D isca-rried.

B is the steam-wheel, which is cylindrical in form. This wheel is recessed around its entire periphery, to forni a peripheral channel, E, leaving tlangcs-f, one upon either side of said channel. These flanges serve to guide the valves in their sliding movement, and also to retain the steam in said channel, thus rendering the device more positive and powerful in its action.

F F are valve-slots cnt through the body of (No modeL the wheel, upon lines radiating outward from its center and terminating at the base of the dangesf. At the outer ends of the slots F the narrow opening F', or vert-ical slot formed in the inner walls of each of the flanges j', affords a communication with the interior of the peripheral channel of the steam-wheel and forms a vguide for the outer ends ofthe valves. It will thus be seen that the slots for the valves do not extend through the sides ofthe lianges forming the sides of the peripheral channel, and thus the said channel is rendered perfectly steamtight, which would not he the case were the slots extended through the sides of the flanges.

The inner faces of the cylinder-heads are furnished with cam-grooves G G, which are indicated by dotted lines in Fig. l of the drawings.

Each of the steam-valves c is provided with a dat outer end, adapting it to iit within the narrow opening F. The opposite end of the valve is provided with projecting necks c, which ii't within the grocved eccentric cams upon the inner faces of the fixed cylinderheads. The valve is also provided with the shoulder c', which, by contact with the outer ends of the slots F, checks the outward throw of the valve.

The forms of the eccentric grooves or cams upon the inner faces of the cylinder-heads, and within which the projections or pins c" of the sliding valves are t-ted, are such as to cause t-he valves to move automatically within the slots F. The outer end of each valve when closed extends across the peripheral channel and terminates at the extreme circumference of the wheel. In order to insure aclose joint and render the valve more effective, the fiat or outer end of the same is made wider than the peripheral channel, its outer edges fitting within narrow grooves upon the inner sides of the flanges forming the sides of t-he peripheral channel.

H represents the steam inlet-passage,.and H the exhaust-pipe. The packing-block c and packing-ring a serve to securely prevent leakage and confine the steam to its proper course within the peripheral channel.

A' portion of the inner edge of the case-ring upon the side of the steam-wheel which is opposite the exhaust-pipe is provided with an inwardly-projecting ylange, d, which tits securely within the peripheral channel and serves to steady the wheel and in a measure prevent vibration.

In operation the steam enters the peripheral channel through the inlet-pipe H. Its passage in one direction, being prevented by the shoulder d and packing-block a', its force is expended against the flat face of the valve which extends across the peripheral channel. The wheel is thus turned until the valve has passedv the entrance to the exhaust-passage, where th'e steam escapes, and the next succeeding valve is closed or forced out into the peripheral channel by reason of the engagement ot' its pins with the cam-grooves, to ,receive the steam from the inlet, Whilethe valve which has discharged its steam into the eX- haust is drawn back into the Wheel by reason of its pins traveling in the camgrooves, as will be readily understood.

Although I have shown and described an engine provided with four valves, it is evident that the number may be Varied and the form of the camgrooves in the cylinder-heads varied so as to operate the valves without departing from the spirit of my invention.

I am aware of the Patents Nos. 225,226 and 227,753, and make no claim to the construe tion shown therein as forming a part of my invention.

Having thus discrihed my invention and set forth its merits, what I claim as new is-` 1. In a rotary engine, substantially as described, a revolving steam wheel having formed therein a peripheral channel, coinbined with the ease-ring, having formed integral therewith an inwardly-projecting flange, b, fitting in and partially closing said channel, substantially as and for the purpose specified.

2. In a rotary engine, substantially as described, the combination, with a revolving steam wheel having a peripheral channel formed therein between the anges f, of a case-ring provided with inwardly-projectirg iiange b, Constructed to close a portion of said channel,and provided with a recess to receive a packing-block, and the packing-block a inserted in said recess and projecting beyond the edges of said flange, as and for the purpose specified.

3. In a rotary engine, substantially as described, a revolving steam-wheel provided with a peripheral channel and slots, as described, combined With valves, as c, adapted to slide in said slots, and provided with shoulders c', constructed to limit the outward throw of said valves, as set forth.

4. In a rotary engine, substantially as de scribed, the steam-wheel B, recessed around its entire periphery to form a peripheral channel, E, having langesfsurrounding said channel upon either side,and having slots F formed in the body of said wheel and terminating at the base of said flanges, and slots F formed in the inner walls of said iianges, combined with the valves c, sliding in said slots in the wheel and guided by the slots in the flanges, as set forth.

5. In a rotary engine, substantially as described, a case-ring made in two parts, with an exhaust-port through one part and the other part formed with an inwardly projecting iiange, d, having shoulders d', and a packingblock, et, inserted in a recess in said iiange,

and a steam-inlet through said part adjacent to said shoulder, substantially as herein shown and described.

In testimony whereof I afx my signature in presence of two witnesses.

GEORGE E. TOLIVER.
